Confirmed Nursery Protocol - aphis

to go through a car wash that has the ability to clean the undercarriage before proceeding to
another work site. If a car wash is not available, avoid driving onto the next work site. To ensure
the entire surface of the tires are cleaned it will also be necessary to move the vehicle forward a
foot or so to permit cleaning of the portion of the tire in contact with the ground.
The tires (or other parts in contact with the soil or plants, such as the bed of trucks) of vehicles
must be cleaned of loose soil and plant debris and disinfested with the appropriate labeled products
before leaving the infested site. Any efficacious product labeled for use on non-porous surfaces
may be used on tires or vehicle undercarriages.
A portion of the vehicle must be designated as a “clean area” where clean work supplies and
equipment can be kept. A designated “dirty area” of the vehicle such as the trunk of the car or a
specified enclosed area of a truck bed must also be identified for use to hold double bagged
clothes or dirty equipment that require cleaning. In situations where pool vehicles are used, the
work site should adopt a set procedure for all personnel.
Nursery Personnel
Nursery personnel routinely come in contact with potentially contaminated soil, plants and
organic matter and this requires the personnel to address a number of biosecurity measures. If
the inspection site has distinct levels of biosecurity for different areas in the nursery, it is
necessary to be aware of this situation. Work should always be completed working from the
areas of lowest to highest risk.
Access:
Access to infested areas and hold areas should be limited, as much as possible, to personnel and
employees. Everyone entering and leaving the nursery site must scrape off loose pieces of soil
into the destruction block. Those working with, or in contact with suspected infested material
(including plants), must wash hands using soap or approved disinfectant immediately after
completion of task. There are no products currently labeled for use on porous materials for
Phytophthora control.
• Personnel should not have access to production areas of the nursery after entering the
destruction block on the same day.
• A disinfectant foot bath should be placed and used by personnel entering and exiting the
quarantine area and entering and exiting the destruction block at the infested nursery site,
where the movement of soil or plant debris on footwear is likely. The foot bath must be filled
with fresh disinfectant at least on a daily basis or more frequently if contaminated with dirt or
debris, in accordance with label directions. Use of disposable shoe covers may be used in lieu
of a footbath, if disposed of immediately upon exiting from the quarantine area or destruction
block. The disposable shoe covers must be placed in bags and incinerated or deep-buried.
• Do not visit other nursery sites in potentially contaminated work clothing and footwear.
